head to head
Sniper Elite: Resistance asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
Methodical infiltration planning paid off by one well-compensated rifle shot.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Sniper Elite: Resistance leans Execution (Practiced Mastery).
Sniper Elite: Resistance leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Sniper Elite: Resistance
Ballistics-compensated shots and stealth timing need steady hands
Sniper Elite: Resistance leans clearly harder on reads.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Sniper Elite: Resistance
Invasion mode adds occasional human cat-and-mouse
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Sniper Elite: Resistance
Patrol details are scripted-but-unknown on first infiltration
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Sniper Elite: Resistance
Route planning, sound masking and shot setups reward study
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
